I took my son with me when he was 6 months old. He just fell asleep. He just considered it a noisy car ride. I put his carrier foward facing in a C-152 and it worked fine (it wouldn't fit backwards).

I tried to slice some foam earplugs in half to make them fit ijn this ear, but he just pulled them out. I have heard that the wax earplugs designed for swimming work well, just do NOT insert/readjust them up at altitude (4,000 plus).

Now I have a child sized headset for him, but he just pulls it off his head and chews on the cord.
